Building the future health workforce: outreach pathways and the Holistic Ecosystem Model

Healthcare workforce shortages and inequities in access to medical education remain persistent global challenges. Expanding participation in health professions education has become a central strategy for strengthening healthcare systems and improving population health outcomes. This perspective applies the Holistic Ecosystem Model (HES) as its central analytical framework to examine outreach initiatives across the United States, the United Kingdom, Australia, and Singapore. The HES conceptualizes pathways into medicine as dynamic systems shaped by four interacting layers: the learner pathway, educational structures, institutional systems, and community and policy environments. Viewing outreach through this ecosystem lens reveals why piecemeal interventions so often fall short-and what more coordinated, systemic strategies might achieve.
